FULL PRODUCT VERSION :

A DESCRIPTION OF THE PROBLEM :
I have supporting localization of standart Swing dialogs in russian language for distributing with our product. In previous version of JDK you can use both '.class' and '.properties' format of resource. For samplifity we used '.properties' format, but in Mustang this is not working - only '.class' format are supported.

The root of the problem is code in sun.util.CoreResourceBundleControl, which are used in Swing to load bundles:

public List getFormats(String s) {
  return java.util.ResourceBundle.Control.FORMAT_CLASS;
}

If this is intentional change of the behavoir, then documentation should be updated.



REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Use '.class' format of resource bundles
